Private ADHD assessment in the UK: the complete 2026 guide
Waiting lists for an NHS ADHD assessment now run into years in many parts of England, and some areas have started capping how many assessments they'll fund. If you're thinking about going private, this guide walks through the whole thing: what happens, what it costs, how medication works afterwards, and how to pick a provider you can trust.
Why so many people are going private
Demand for ADHD assessment has grown far faster than NHS funding. Around 960,000 people are now waiting for an NHS ADHD assessment in England, and most adults on those lists have been waiting more than a year.
Those caps matter. Under the 2026/27 NHS payment rules, local health boards (called ICBs) can set a fixed budget for each Right to Choose provider. When the money runs out, providers stop booking new NHS assessments, sometimes for the rest of the year. That's why a lot of people who were told "you'll be seen in a few months" are now hearing "we can't give you a date".
Check Right to Choose first
If you live in England, you have a legal right to ask your GP to refer you to an approved private provider for an NHS-funded ADHD assessment. This is called Right to Choose. It's free, and in some areas the wait is still five or six months.
The catch is that it's become a postcode lottery. In areas with caps, waits can stretch past a year, and some providers have paused new bookings altogether. Right to Choose also doesn't exist in Scotland, Wales or Northern Ireland, and there are fewer options for children.
The private ADHD journey, step by step
1. Assessment
This is a long, structured conversation with a specialist, usually between an hour and a half and three hours. You'll talk about your childhood, school, work, relationships and how things affect you day to day. Most clinics use standard questionnaires, and many will ask for input from someone who knew you growing up, or for old school reports if you have them.
Most assessments can be done online. Some people prefer to go in person, especially for children.
2. Diagnosis and report
You'll get a written report explaining the outcome and the reasons behind it. A good report clearly follows the national guideline for ADHD, NICE NG87. That matters later if you want your GP to take over your prescriptions.
3. Titration (if medication is right for you)
Not everyone diagnosed with ADHD takes medication. If you and your clinician decide to try it, the next stage is titration: finding the right medicine and dose. More on that below.
4. Shared care and ongoing reviews
Once you're on a stable dose, your specialist can ask your GP to take over prescribing. After that, most people have an annual review.
What it costs
Headline prices can be misleading, because many clinics quote the assessment on its own. Here's the fuller picture, and you can see what 20 UK clinics actually charge in our price check.
| Stage | Typical private cost |
|---|---|
| Assessment | £500 to £2,500 (many around £800 to £1,300) |
| Titration reviews | £100 to £300 each |
| Private prescriptions | £70 to £180 a month |
| Annual review | Often £300 to £500 |
| Total to a stable dose | Often £1,500 to £3,500 |
Those are the usual ranges. For the actual figures, we went through the websites of 20 UK clinics and recorded every price they publish: see what 20 clinics actually charge for a private ADHD assessment.
Titration and medication
Titration means starting medication at a low dose and adjusting it over several weeks or months, with regular check-ins. Your clinician will monitor your blood pressure, pulse and weight, and ask how the medication is affecting your focus, sleep, appetite and mood.
Most first-line ADHD medicines are stimulants, such as methylphenidate or lisdexamfetamine. There are non-stimulant options too, such as atomoxetine. Your clinician will talk through what's suitable for you.
One thing to check: some providers assess but don't prescribe. Psychologists, for example, can diagnose ADHD but can't prescribe medication. If you want the option of medication, make sure your provider offers titration directly or through a named partner. Our guide to ADHD titration explains how it works. Our full guide to shared care and titration goes into more detail.
Shared care with your GP
Paying for private prescriptions every month adds up. Shared care is the arrangement where your GP takes over prescribing once you're stable, so you pay the standard NHS prescription charge instead.
Your GP doesn't have to agree, and acceptance varies a lot between practices and areas. You'll usually have a better chance if your provider is registered with the CQC, follows NICE guidance, and supports the shared care request.
How to choose a provider
- The clinician is registered: GMC for doctors, NMC for nurses, HCPC for psychologists
- The clinic is registered with the CQC (if it's in England)
- Assessments follow NICE guideline NG87, with a full written report
- Titration is offered, directly or through a named partner
- They support shared care requests to your GP
- Prices are clear, including the report, titration and reviews
- They'll tell you a realistic wait before you pay anything
You can check a doctor on the GMC register and a clinic on the CQC website in a couple of minutes.

Common questions
How long does a private ADHD assessment take?
The assessment itself usually takes between an hour and a half and three hours. Getting an appointment is typically a matter of weeks with a private provider, compared with a year or more on many NHS lists.
Do I need a GP referral for a private ADHD assessment?
No. You can book a private assessment directly. You'll need a GP referral if you want to use Right to Choose for an NHS-funded assessment.
Is a private ADHD diagnosis valid?
Yes. A diagnosis from a properly qualified, registered specialist is a valid diagnosis. Whether your GP takes over prescribing is a separate decision, known as shared care.
Does private health insurance cover ADHD assessment?
Usually not. Most standard private medical insurance policies exclude ADHD, so check your policy wording or ask your insurer before booking.
Can I stay on the NHS waiting list while I go private?
Yes. Booking privately doesn't remove you from an NHS or Right to Choose waiting list.
